Sega Mega-CD (ja:メガ�E��E�) known in the USA and Brazil as Sega CDsegacd and in South Korea as CD Aladdin Boy (ko:CD �E�라�E�E�E��E�), is a 16-bit CD add-on for the Sega Mega Drive. It was released in 1991 in Japan, in order to take down the PC Engine add-on, the CD-ROM² System. The MCD did not take down the PCE and Super Famicom's fame in Japan, but it did strong sales against the TurboDuo in US. It was discontinued in 1995 in US and Europe, and in 1996 in Japan.
